基于“FPGA+DDS”的通信背景信号生成系统设计

The Design of Communication Background Signal Generation System on "FPGA+DDS"

本文介绍的是动态通信背景信号生成系统的设计与研究。首先从理论上分析了几种背景信号生成的设想,比较其优缺点,然后重点描述了"FPGA+DDS"方案。此方案虽然总体控制单元设计较为复杂,但兼顾运算速度和灵活性,既满足底层信号处理算法要求,又满足高层系统控制分析的需要,成为此系统设计方案的首选。

This thesis is about the design and study on Dynamic Communication Background Signal Generation System. First, it analyses the various kinds of background signals generation on theory, compares their strengths and weaknesses,and then focuses on the description of the ＂FPGA＋DDS＂ project. In this project the design on whole controlling unit is complicated , but it operates efficient and flexible, and it not only contents the demand of bottom signal processing arithmetic as well as the requirement of high system control analysis .Consequently, the project is preferred.
